Application filed April 19, 1923. Serial mi. 633,137.

To all whom z'tmay concern:

Be it'knownthat ,1, CHRIS JOHNSON, a citizen of the United States, residing at Fairview, in the county of Richland, State of Montana, have invented a new and useful Churn; and I do-hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

, The'invention relates to churns, andhas for its object to provide a device of this character comprising a receptacle having a removable cover, which cover is provided with a dependent agitator, which agitator is rotated through the'medium of an operating shaft, which operating shaft is provided carried'by the cover and withv a gear carried by the agitator. A further object is to rotatably mount the operating shaft in the agitator shaft, which agitator shaft carries a gear at its upper end. Also to mountthe upper end of the agitator shaft in anti frictional bearings, thereby reducing the'friction to a minimum.

A further object is to provide the annular rack with an outwardly extending handle adapted to be grasped by the operator for steadying the device during the rotation of y the operatingshaftby means of an operating crank. I

With the above and other objects 1n vlew the invention'resides in the combination and arrangement. of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes tor shaft showing adjacent mechanism in section.

Referring to the drawing, the. numeral 1 designates the receptacle of the churn and 2 a removable cover. Rotatably mounted in a roller bearing 3 of the cover 2 is a vertically disposed hollow agitator-shaft 4:,

which shaft extendsv downwardly into the receptacle 1 and is provided with a plurality of agitating arms 5, which are horizontally disposed whereby material within the chamher 6 of the receptacle will be agitated upon rotation of the hollow shaft at. The inner wall of the receptacle 1 is provided with vertically disposed ribs 7, which ribs during the churning operation cause eddys in the milk and consequently assists in the churning operation. Secured to the upper end of the hollow shaft 4: by means of a pin 8 is a gear 9, with which gear, a larger gear 10 meshes. Gear 10 is pivotally mounted ona shaft 11 carried by an arm 12, and also meshes with an annular internal gear 13 carried by the. cover 2. The arm' 12 is secured to a vertically disposed operating shaft 14, and it will be seen that when the shaft 14:, is rotated and consequently a gear 10 will be rotated by the internal gear 13 and at a rapid speed of rotation- Gear 10 meshes with the small gear 9 carried by the hollow shaft 4, and consequently the hollow shaft 4: is rotated at a rapid speed, thereby allowing a churning operation to take place illit' minlmum amount of time, and with a relatively slow rotation of the operatlng The gear. means also increases shaft 14. the power imparted on the agitator,thereby making the churning operation less laborious. Operating shaft 14 extends downwardly into the hollow agitator shaft 4, and

has a bearing therein. Shaft 1st at its upper end is provided with a horizontally disposed crank 15 adapted to be grasped by the operator during the churning operation. However, to allow the operator to further brace and hold the device during a churning operation, the internal gear 13 is provided with an outwardly extending handle '16, which may be grasped by one hand of the operator during the churning operation. The receptacle 1' is provided with spaced clamping members 17, which clamping members engage over the top Qand securely clamp the top on the receptable, thereby additionally preventing the movement of the top during a churning operation.

' From the above it will be seen that'a gear operated agitating device is provided for churns, wherein the maximum amount of power is applied to the agitating shaft, and

.an increased speed of rotation is imparted to the agitator shaft during the rotation of the crank operated shaft, thereby insuring a rapid churning of milk within the churn.

The invention having been set-forth, what is claimed as new and useful is A stirrer actuating device comprising a support, a vertically disposed hollow shaft rotatably mounted in a bearing of the support, an operating shaft rotatably mounted in the hollow shaft, a gear secured-to said hollow shaft above the support, an internal gear carried by the support and extending around the shafts, a radially disposed arm carried by the operating shaft, a gear carried by the arm and meshing with the internal gear and the gear carried by the hollow shaft and a crank carried by the operating shaft.

In testimonywhercof I have signed my name to this specification in the presence of 20 two subscribing witnesses.

CHRIS JOHNSON.
